What law is this?
An object in motion (or at rest) will tend to stay in motion (or at rest) unless acted upon by an external unbalanced force
Newton's first law of motion / law of inertia

A 200g ball takes 5 seconds to fall 50m. How long will this take an object that is twice the mass?
5 seconds - mass does not affect an object's acceleration due to gravity.
temperature is a measure of an object's
a) average potential energy
b) average kinetic energy
c) total thermal energy
d) internal energy
B
Who is this?
This scientist is best known for his contributions to our understanding of the laws that govern motion.
Isaac Newton
How many rooms are on E block level 1?
5
What is the world record for the most number of forks held in a beard?
126
Identify the correct statement:
A) a longer wire will have less resistance
B) an object at rest on a table has no forces acting on it
C) acceleration is the rate of change of an object's velocity
D) if a process is not 100% efficient, it means energy is not conserved
A heat engine provides 120J in thermal energy from the hot reservoir. If 20J is transferred to the cold reservoir, and 100J is used to do work, determine the efficiency of the engine.
(round to nearest whole number)
= output / input x 100 (%)
= 100/120 x 100
= 83%
Who is this?
This scientist is famous for their contributions to understanding nuclear physics, discovering the elements radium and polonium.
Marie Curie
When was Mr Wade Haynes principal of BSHS? From ___ to ____
2011-2023
For 100 points each:
If someone "cooked", what three meanings could this have?
They have done really well
They have done really badly
They have made a meal to eat
Describe the forces acting on the object by drawing a free body diagram.
upwards normal force, downwards gravitational force (equal and opposite).
No horizontal forces.
Compare the internal energy of a solid and a gas in terms of their particles.
solid - low kinetic (slow particles), high potential (strong bonds)
gas - high kinetic (fast particles), low potential (few / no bonds)
Who is this?
This scientist is well known for their model of the atom that describes electrons orbiting in energy levels or "shells"
Niels Henrik David Bohr
Which house has a wolf as its mascot, and what is its colour?
Which Australian mammal is capable of laying eggs?
Platypus
two 20W bulbs are connected in series to a 40V battery.
What two formulas are used to determine the total resistance of the circuit?
P=VI
V=IR or P=I2R
1kg of -20˚C ice is placed in 2L of 35˚C water. Determine the equilibrium temperature.
0˚C
(the water has enough energy to get the ice to melting point, and a little bit of energy to begin to melt it, but it does have enough energy to melt it completely, so the end product will be slushie icewater)
Q to get ice to 0˚C = 41 kJ
Q to fully melt ice = 334 kJ
Q to get water to 0˚C = 293 kJ
Who is this?
This scientist was famous for working out how mechanical work can heat up water.
James Joule
